El objetivo fue determinar la relación entre el aporte de progesterona exógena a través de un dispositivo intravaginal (CIDR) con la fertilidad, durante el proceso de reconocimiento materno y el mantenimiento de la gestación después de la inseminación artificial. Las ovejas fueron sincronizadas mediante el uso de un dispositivo intravaginal impregnado de un progestágeno natural (CIDR), por un periodo de 9 días. Dos días antes del retiro del dispositivo se aplicó 15 mg de prostaglandina F2α, vía intramuscular. Las ovejas fueron distribuidas al azar en dos grupos,  para constituir los siguientes tratamientos: 1) ovejas inseminadas sin progesterona (P4) adicional (IASP) y 2) ovejas inseminadas que recibieron  progesterona exógena (P4) (IACP) a través de un...

The beliefs of mothers in southern Brazil regarding risk-factors associated with congenital abnormalities
Provedor de dados: Genetics and Molecular Biology
Autores: Garcias,Gilberto de Lima; Schüler-Faccini,Lavínia.
We describes a study in which conventional wisdom about congenital malformations was investigated, the two main objectives being to list mothers' ideas by comparing six well-known causes of congenital abnormalities (ingestion of alcoholic beverages, smoking tobacco, drug use, marriage between relatives (consanguinity), rubella infection, maternal age) with explanations current in the general population and to discover the most common fallacies held by the general population concerning such abnormalities. The data were collected from 1 January to 31 December 1995 during a population study in which mothers were interviewed in hospitals in the city of Pelotas (population 400,000), Rio Grande do Sul state, Brazil. On each day of the study, the first three...

Abstract Congenital anomalies are already the second cause of infant mortality in Brazil, as in many other middle-income countries in Latin America. Birth defects are a result of both genetic and environmental factors, but a multifactorial etiology has been more frequently observed. Here, we address the environmental causes of birth defects – or teratogens – as a public health issue and present their mechanisms of action, categories and their respective maternal-fetal deleterious effects. We also present a survey from 2008 to 2013 of Brazilian cases involving congenital anomalies (annual average of 20,205), fetal deaths (annual average of 1,530), infant hospitalizations (annual average of 82,452), number of deaths of hospitalized infants (annual average of...

Abstract In 1990, the first Teratogen Information Service in Brazil (SIAT) was implemented in the Medical Genetics Service at Hospital de Clinicas de Porto Alegre. SIAT is a free-to-use information service both to health professionals and the general population, especially to women who are pregnant or planning pregnancy. The main objective of this paper is to present the activities of SIAT in its initial years (1990-2006), compared to those in the last decade (2007-2017). In addition we review the scientific contribution of SIAT in the field of human teratogenesis. Since 1990, SIAT received 10,533 calls. Use of medications were the main reason for concern, accounting for 74% of all questions, followed by other chemical exposures (occupational, cosmetics,...

Trace element levels in foetus-mother pairs of short-beaked common dolphins (Delphinus delphis) stranded along the French coasts
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Lahaye, V; Bustamante, Paco; Dabin, W; Churlaud, C; Caurant, Florence.
Tissues of foetus-mother pairs of common dolphins (Delphinus delphis) stranded along the French coasts (Bay of Biscay and English Channel) were analysed for their Cd, Cu, Hg, Se and Zn contents. In the kidneys, foetal Cd levels were extremely low, and strong relationships between Cu and Zn suggested the involvement of metallothioneins since early foetal life. The results also indicated a limited maternal transfer of Hg during pregnancy since levels in the tissues of foetuses were below 1 mu g g(-1) w.wt. However, hepatic Hg levels in foetuses increased with body length, and were also proportionate to maternal hepatic, renal and muscular Hg levels. Lastly, affinities between Hg and Se in tissues would participate in Hg neutralisation in both mothers-through...

Although being used for years in the treatment of tuberculosis, no data are available in the literature on the safety of pyrazinamide during pregnancy. Accordingly, we aimed to make a first approach to this problem by evaluating the effects of this drug administered during the entire pregnancy of albino rats. Fourty female, EPM-1 Wistar albino rats of about 250 g b.w. were used. Upon conception (day zero of pregnancy) the animals were randomly divided in 4 groups of 10 rats each and labeled as follows. Controls (C), animals treated with the drug vehicle (destilled water); experimental groups (E1, E2 and E3), animals treated with 35, 105 or 315 mg/kg b.w. pyrazinamide by gavage (oral route) once daily up to the term (20th day of pregnancy). Drug or vehicle...

Autores: Vilaça Júnior,Paulo Estevao Araújo; Teixeira,Alvaro Aguiar Coelho; Wanderley Teixeira,Valéria; Moraes,Eleonora de Figueiredo; Araújo,Ana Claudia Carvalho de; Maia,Carina Scanoni.
The glucocorticoid dexamethasone has been largely used due to its anti-inflammatory effect. However, several authors report that the excessive exposition to it during pregnancy may cause a retard in the development in several tissues, mainly: liver, lungs and kidneys. But, the majority of the works are done with the application of dexamethasone in the late periods of pregnancy. Because of the lack of researches that evalúate the effects in the beginning of gestation, this paper aimed at evaluating the effect of dexamethasone administered in the initial phase of pregnancy, o ver the morphology of neonates rat. It was used 10 albino rats (Rattus norvegicus albinus) aged 90 days from the lineage Wistar. The female were coupled and divided in two groups: Group...

Chronic stress by immobilization during pregnancy may cause alterations in mechanisms maintaining homeostasis in the adrenal gland. The objective of this study was to quantify cellular proliferation index in the adrenal cortex during pregnancy second half and assess the effects of chronic stress on it. Adrenal cortex proliferation index in stressed rats showed a significant decrease at 12 and 17 days of gestation, while at day 21 it did not show differences with the control treatments. Moreover, proliferation index of reticular zones in control and experimental rats, exhibited a significant reduction in comparison to glomerular and fascicular zones of adrenal cortex during the three gestation days studied. In conclusion, chronic stress by immobilization...

Provedor de dados: International Journal of Morphology
Autores: Kazemi,Masoomeh; Tekieh,Elaheh; Golabi,Sahar; Sahraei,Hedayat.
Based on previous studies, a variety of bioenvironmental elements including inappropriate nutrition, diseases, infections, stressors, and medications are involved in epigenetic changes. Drug abuse is one of the most important causes of epigenetic changes and a concern in today's world. Studies have shown that morphine use by pregnant mothers causes several disorders in mothers in addition to transferring abnormalities to the next generation (placenta and embryo). Epigenetic factors such as morphine cause changes in gene expression in placenta as the first embryonic defense barrier. Because placenta does all the nutritional exchanges between mother's and embryo's blood, placental health guarantees normal embryonic development. Many studies have been...

Human immunodeficiency virus (HIV) infection is in growing incidence throughout the world. Due to the increasing proportion of affected women in reproductive years, the association of pregnancy with HIV infection becomes a matter of major Public Health concern. Antiretroviral drug administration turned out to be imperative during pregnancy in order to prevent the vertical transmission; accordingly, new antiretroviral drugs and anti-HIV drug associations have been tested in experimental pregnancy models before they are approved to be included in protocols for use during human pregnancy. Lamivudine is a nucleoside reverse transcriptase inhibitor currently used in association with other antiretrovirals. Since no data exist on the perinatal safety of...

There are few long-term data on which to base decisions of drug management of HIV infection in pregnancy. The determination of safe medications must take into consideration the need for certain drugs and the possibility of inadvertent fetal exposure because of unplanned pregnancies. The aim of this study was to evaluate the effects of foscarnet on the entire period of rat pregnancy. Female pregnant rats were randomly assigned to four treatment groups (n = 10): one control (C) ­ treated with the drug vehicle (bidestilled water) and three experimental groups (E1, E2 and E3) ­ treated with 180, 360 or 720 mg/Kg of foscarnet, respectively.

Autores: Dorce,Ana Leticia C; Dorce,Valquiria AC; Nencioni,Ana Leonor A.
BackgroundScorpion envenoming is a public health problem in Brazil, whereTityus serrulatus and T. bahiensisare considered the most dangerous scorpions. They are well adapted to urbanized environments, and there is an increasing probability of human exposure to these venoms, including during pregnancy. Not much is known about the effects of prenatal exposure to the venom, and no information is available to aid in the rational treatment of victims stung during pregnancy. Thus, this study aimed to investigate whether venom from the scorpion T. bahiensis administered once to pregnant female rats at a dose that causes a moderate envenomation may lead to deleterious effects on the reproductive performance of the dams and on the development of their offspring....

Abstract Scorpion envenomation is a public health problem, especially in tropical and subtropical countries. Considering the high incidence of scorpionism in some areas, pregnant women and nursing mothers may be possible victims. Scorpion stings alter the release of neurotransmitters and some cytokines. These mediators act as organizers and programmers in the adequate formation of the nerves, and non-physiological concentrations of them during the brain organization originate disorders and diseases that can appear later in the life of the individual. Despite the importance of this subject, there are only a few studies showing the effects of scorpion venom on maternal reproductive development, in the morphology and physical and behavioral development of...

Tityus serrulatus is the most venomous scorpion in Brazil; however, it is not known whether its venom causes any harm to the offspring whose mothers have received it. This study investigates whether the venom of T. serrulatus may lead to deleterious effects in the offspring, when once administered to pregnant rats at a dose that causes moderate envenomation (3mg/kg). The venom effects were studied on the 5th and on the 10th gestation day (GD5 and GD10). The maternal reproductive parameters of the group that received the venom on GD5 showed no alteration. The group that received the venom on GD10 presented an increase in post-implantation losses. In this group, an increase in the liver weight was also observed and one-third of the fetuses presented...

Hyperthelie, Wurfgröße und Trächtigkeitsdauer bei der Unterfamilie Tenrecinae Cabrera, 1925 (Mammalia: Insectivora: Tenrecidae), nebst Bemerkungen zur Längsstreifung der Gattung Hemicentetes
Provedor de dados: Naturalis Digital Academic Repository
Autores: Poduschka, Walter.
In a comparison of basic reproductive variables (number of teats, litter size, and duration of pregnancy) in the Madagascan Tenrecinae, some striking features (hyperthelia, litter size) are observed in Tenrec ecaudatus Lacépède, 1799 and the genus Hemicentetes Mivart, 1871. These variations are compared to Setifer setosus Froriep, 1806 and Echinops telfairi Martin, 1838. Tenrec ecaudatus gives birth to litters at intervals shorter than what was once believed to be the duration of pregnancy. This could be due either to superfetation, or to giving birth to one litter in two or more installments. The longitudinal stripe pattern of the genus Hemicentetes is interpreted as a mimicry of the sympatric, equally striped, juvenile Tenrec ecaudatus. The latter...

The objective of this study was to evaluate the efficiency of cyclic and acyclic progesterone-treated recipient mares in a commercial embryo transfer program. Acyclic recipients were treated with decreasing amounts of estradiol cypionate (ECP® - Pfizer Saúde Animal, São Paulo, Brazil), followed by 1500 mg of a sustained-release progesterone injection (P4LA150® - Laboratórios B.E.T., Rio de Janeiro, Brazil). Out of all 1506 embryo recovery attempts performed, 59.36% were positive (894/1506). Pregnancy rates of cyclic and acyclic mares were, respectively, 44.12% (319/723) and 57.68% (139/241) - higher in acyclic recipients under progesterone treatment. Embryo loss was similar between groups (9.72% 31/319 vs. 11.51% - 16/139). When fertility data on acyclic...

Autores: Souza,Felipe Amorim Caetano de; Muniz,Joel Augusto; Fernandes,Tales Jesus; Cunha,Fabiana Oliveira; Meirelles,Sarah Laguna Conceição; Souza,José Camisão de; Moura,Raquel Silva de.
ABSTRACT The objective was to evaluate the accuracy of six body weight (BW) estimating methods in Mangalarga Marchador horses (MM) (n = 318): method A - tape placements at three different positions around the thoracic girth; B - Crevat and Quetelec's formula; C - Hall's formula; D - Hintz and Griffiths’ table; E - Santos’ table; and F - Cintra's formula. For additional analyses, gender, age, and gestational stage were considered. Estimated average BW was compared to the actual scale weight by the paired T test, mean predicted error, and determination coefficient. In the general population, methods A (position 3), B, and C estimated BW that were different from that of the scale. Method A, at positions 1 and 2, was more accurate in predicting the scale...

Energetic metabolism in fasting sheep: regularization of metabolic profile by treatment with oral glucose, with prior handling of gastric groove
Provedor de dados: Revista Brasileira de Zootecnia
Autores: Martín-Alonso,María José; Escalera-Valente,Francisco; Cal-Pereyra,Luis G.; Benech,Alejandro; Alonso,María Pilar; González-Montaña,José Ramiro.
ABSTRACT The objective of this research was to evaluate a possible corrective measure against negative metabolic states, as occurs in the advanced stage of gestation in ewes, and that sometimes produces a disease called pregnancy toxaemia. In the present research, we found that the joint administration of i.v. lysine-vasopressin (0.08 IU/kg body weight, BW) and an oral glucose solution (50 g) produces an increase in blood glucose, which persists for some time (up to 6 h); therefore, it could be used in the treatment of pregnancy toxaemia. This therapy is based on the fact that lysine-vasopressin induces gastric groove closure in adult ruminants, enabling orally administered glucose to reach the abomasum directly, from where it rapidly passes into the...

Autores: Boneventi, Priscila; Baroneza, José Eduardo; Moreira, Camila Queiroz; Santos, Debora Cristina D. Meirelles dos; Salles, Maria José Sparça.
Farm workers at Brazilian tobacco plantations are frequently exposed to toxic chemicals and eventually became contaminated with these products. Flumetralin is a inhibitor of axillary bud growth on tobacco and the effects of gestational exposure should be investigated since many pesticides cross the placental barrier and cause birth defects. The aim of this study was to investigate maternal and fetal effects caused by inhalation of Flumetralin. Pregnant Swiss mice inhaled Flumetralin for 10 or 20 minutes on the seventh day of pregnancy. On the 18th day, animals were euthanized and subjected to laparotomy for removal of the uterus and embryos. The uterus was weighed and the embryos were examined. Fetuses of both treatments showed visceral changes in the...

Citrus aurantium L., commonly known as bitter orange, is widely used in folk medicine, but there is little data in the literature about the effects on pregnancy. The aim of the present study was to evaluate the influence of essential oil obtained from fruits of Citrus aurantium on the maternal reproductive outcome and fetal anomaly incidence in rats. Pregnant Wistar rats were randomized into four groups (n minimum = 12 animals/group): G1 = control, G2 to G4 = treated with essential oil from C. aurantium at dose 125, 250 and 500 mg/kg, respectively. Rats were orally treated, by gavage, with plant essential oil or vehicle during pre-implantation and organogenic period (gestational day 0-14). On gestational day 20 the rats were anaesthetized and the gravid...

ABSTRACT The aim of this study was to compare two models of swimming applied to pregnant rats born small for pregnancy age (SPA). Diabetes was chemically induced in adult female rats to develop an inadequate intrauterine environment, leading to birth of a SPA offspring. In adulthood, the female SPA rats were mated and submitted to different swimming programs. The exercise program 1 (Ex1) consisted of swimming for 15 minutes, followed by 15 minutes of rest and another 15 minutes of swimming, 3 days a week before and during pregnancy. Another program (Ex2) was applied during 60 minutes uninterrupted a day, 6 days/week during pregnancy. The pregnant rats presented no interference on body weight and glycemia. The rats submitted to Ex2 model showed decreased...

ABSTRACT Several studies present different methodologies and results about intensity exercise, and many of them are performed in male rats. However, the impact of different type, intensity, frequency and duration of exercise on female rats needs more investigation. From the analysis of blood lactate concentration during lactate minimum test (LacMin) in the swimming exercise, the anaerobic threshold (AT) was identified, which parameter is defined as the transition point between aerobic and anaerobic metabolism. LacMin test is considered a good indicator of aerobic conditioning and has been used in prescription of training in different exercise modalities. However, there is no evidence of LacMin test in female rats. The objective was to determine AT in...

The phosphatidylinositol 3-kinase and mitogen-activated protein kinase pathways mediate β cell growth, proliferation, survival and death. We investigated whether protein restriction during pregnancy alters islet morphometry or the expression and phosphorylation of several proteins involved in the phosphatidylinositol 3-kinase and mitogen-activated protein kinase pathways. As controls, adult pregnant and non-pregnant rats were fed a normal-protein diet (17%). Pregnant and non-pregnant rats in the experimental groups were fed a low-protein diet (6%) for 15 days. Low protein diet during pregnancy increased serum prolactin level, reduced serum corticosterone concentration and the expression of both protein kinase B/AKT1 (AKT1) and p70 ribosomal protein S6...

ABSTRACT There are studies on electrocardiogram (ECG) in several breeds of horses, which highlights the growing importance of cardiology in this species. But few authors have addressed the influence of pregnancy on the cardiac physiology of the mare, and specifically, there are no studies on the Mini-horse breed, as well as no correlation of body weight (BW) and heart rate (HR) with electrocardiographic parameters in this breed. The aims of this study were to determine the effects of pregnancy on ECG parameters and to examine the relationships between these variables and body weight (BW) and heart rate (HR). A total of 203 animals were used, including 143 females (66 pregnant) and 60 males. Electrocardiographic examinations were performed by computerized...

Autores: Bozzo,Andrea; Soñez,Carlos Alberto; Mugnaini,María Teresa; Pastorino,Isabel Cecilia; Rolando,Alicia Nélida; Romanini,María Cristina; Gauna,Héctor Fernando.
Chronic stress by immobilization during gestation can alter several mechanisms that maintain homeostasis in adrenal gland. The aim of this work was to quantify the apoptotic index of adrenal cortex during mid-pregnancy and to prove cytological characteristics by electron microscopy. The apoptotic index did not present significant differences between the adrenal cortex areas of control and experimental rats in any of the three ages studied. The day of gestation influenced significantly on the apoptotic index in both groups. This index increased as gestation progressed. It may be concluded that chronic stress by immobilization might induce the increase of apoptotic index in adrenal cortex as gestation progresses which might be related variations of plasmatic...

Loss of Imprinting (LOI) of IGF2 and over-expressed IGF2 are associated with tumorigenesis. Our previous epidemiological study found a relatively high frequency of IGF2 LOI in healthy mid-gestation pregnant women. The aim of this study is to determine whether the expression of IGF2 is associated with its imprinting status in healthy Chinese pregnant women. The IGF2 imprinting status of 300 pregnant women was analyzed. 20 cases of IGF2 LOI and 20 cases of IGF2 retention of imprinting (ROI) were selected randomly for IGF2 expression analysis. The expression pattern of IGF2 between the group with IGF2 ROI and group with IGF2 LOI in healthy Chinese pregnant women was evaluated by real time PCR and western blot. The result showed no significant differences...

Pre-eclampsia: a life-threatening pregnancy syndrom
Provedor de dados: Brazilian Archives of Biology and Technology
Autores: Brazdova,Andrea; Keprova,Alena; Zidkova,Jarmila; Madar,Jindrich.
Pre-eclampsia is a serious pathological state affecting 5-10% of pregnant women. Currently, it is diagnosed in the second half of pregnancy, particularly after the 20th week. Symptoms mostly correspond to the changes of blood vessels and kidneys. The severity of pre-eclampsia is proportional to symptomatic manifestations, thus the more symptoms present, the higher is of pre-eclampsia development. Although there are several studies dealing with pre-eclampsia pathology, the complete etiology is still unknown. In this review paper, several theories are presented and discussed.

Provedor de dados: Brazilian Jounarl of Veterinary
Autores: Oliveira,Fabrício Singaretti de; Machado,Márcia Rita Fernandes; Canola,Júlio Carlos.
The paca is a South American rodent whose handling, tranquilization or anesthesia offers a large field of research due to rare existing issues. Twelve adult female pacas were used, separated in 6 pen, and were caught with a net made of polypropylene attached to a wire loop and then sent to a room where the abdominal hair clipping was done. Afterwards, the female was placed in an iron bar squeeze cage. The ultrasonography session was made in B mode with a two-frequency sectorial electronic transducer of 5.0 and 7.5 MHz. Intending to reduce the stress caused by the procedures, the tranquilization of females was made with oral taking of diazepam and midazolam maleate. Both presented effectiveness in tranquilization of pacas previously and during sessions,...

Use of assisted reproductive technology to separate sperm from human immunodeficiency virus infected men resulting in pregnancy among serodiscordant couples
Provedor de dados: Brazilian Journal of Infectious Diseases
Autores: Schuffner,Alessandro; Lisboa,Ana Paula; Rosa,Vinicius Bonato da; Silva,Monica Maria Gomes da.
Due to HIV care improvement, discordant couples more frequently seek help in order to conceive their own biological child. Besides the advance of antiretroviral therapy, unprotected intercourse is not a complete safe option, carrying a low but still present risk of HIV transmission. We report 10 serodiscordant couples in whom the male partner is HIV positive, submitted to sperm washing and intrauterine insemination. The procedure resulted in four pregnancies and no HIV transmission to mother or child was observed. Techniques of assisted reproduction can help HIV discordant couples to conceive biological offspring and is a safer option than unprotected intercourse.

This report describes a case of Toxoplasma encephalitis during pregnancy of an HIV infected woman who was severely immunosuppressed (CD4: 17 cells/mm3), had a high viral load (RNA PCR:230,000 copies/ml), was treated with sulfadiazine, pyrimethamine and folinic acid for toxoplasmosis and was being treated with highly potent antiretroviral drugs (AZT, 3TC and nelfinavir) for HIV infection. The newborn was born through an elective C-section, received six weeks of AZT according to the 076 protocol and was clinically normal at birth. Subsequently he had two RNA PCR negatives for HIV, seroreverted and had no clinical or laboratory evidence of congenital toxoplasmosis. Despite the concerns of the use of these combined therapies on the foetus during pregnancy,...

Provedor de dados: Brazilian Journal of Infectious Diseases
Autores: Miranda,Angelica E.; Pinto,Valdir M.; Gaydos,Charlotte A.
Our goal was to determine the prevalence of Trichomonas vaginalis and its associated risk factors in parturient women aged 15–24 years attending Brazilian public maternity units. Participants answered a demographic, behavioral, and clinical data questionnaire. A sample of urine was screened for T. vaginalis. A total 299 women participated in this study. The prevalence rate of T. vaginalis was 7.7% (95% CI: 4.7–10.7%). The factors associated with T. vaginalis were use of illicit drugs OR = 4.70 (95% CI: 1.63–13.56, p = 0.004)] and not attending antenatal care OR = 5.15 (95% CI: 1.15–23.25, p = 0.032)]. These data demonstrate that it is important to discuss how to include routine screening for T. vaginalisduring antenatal care in Brazil.

Provedor de dados: Brazilian Journal of Infectious Diseases
Autores: El Beitune,Patrícia; Duarte,Geraldo; Maffei,Cláudia Maria Leite.
We reviewed colonization by group B Streptococcus beta-haemolyticus of Lancefield (SGB), or Streptococcus agalactiae, in pregnant women, and the consequences of infection for the mother and newborn infant, including factors that influence the risk for anogenital colonization by SGB. We also examined the methods for diagnosis and prophylaxis of SGB to prevent early-onset invasive neonatal bacterial disease. At present, it is justifiable to adopt anal and vaginal SGB culture as part of differentiated obstetrical care in order to reduce early neonatal infection. The rates, risk factors of maternal and neonatal SGB colonization, as well as the incidence of neonatal disease, may vary in different communities and need to be thoroughly evaluated in each country...

Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Sichieri,R.; Silva,C.V.C.; Moura,A.S.
Short stature, a marker for undernutrition early in life, has been associated with obesity in Brazilian women, but not in men. We tested the hypothesis that weight gain during the reproductive years could explain this gender difference. A national two-stage household survey of mothers with one or more children under five years of age was conducted in Brazil in 1996. The subjects were women aged 20 to 45 years (N = 2297), with last delivery seven months or more prior to the interview. The regions of the country were divided into rural, North/Northeast (urban underdeveloped) and South/Southeast/Midwest (urban developed). The dependent variables were current body mass index (BMI) measured, BMI prior to childbearing (reported), and BMI change. Socioeconomic...

In the canine species, the precise mechanisms of pregnancy maintenance and the initiation of parturition are not completely understood. The expression of genes encoding the receptors for estrogen (ERα mRNA) and oxytocin (OTR mRNA) was studied in the endometrium and myometrium during pregnancy and parturition in dogs. Real-time PCR was performed to quantify the levels of ERα mRNA and OTR mRNA in the uterus of bitches during early (up to 20 days of gestation), mid (20 to 40 days) and late pregnancy (41 to 60 days), and parturition (first stage of labor). All tissues expressed ERα and OTR mRNA, and are thus possibly able to respond to eventual estrogen and oxytocin hormonal stimuli. No statistically significant differences in the expression of ERα mRNA were...

Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Brosnihan,K.B.; Neves,L.A.A.; Anton,L.; Joyner,J.; Valdes,G.; Merrill,D.C.
Pregnancy is a physiological condition characterized by a progressive increase of the different components of the renin-angiotensin system (RAS). The physiological consequences of the stimulated RAS in normal pregnancy are incompletely understood, and even less understood is the question of how this system may be altered and contribute to the hypertensive disorders of pregnancy. Findings from our group have provided novel insights into how the RAS may contribute to the physiological condition of pregnancy by showing that pregnancy increases the expression of both the vasodilator heptapeptide of the RAS, angiotensin-(1-7) [Ang-(1-7)], and of a newly cloned angiotensin converting enzyme (ACE) homolog, ACE2, that shows high catalytic efficiency for Ang II...

Cancer patients present high mobilization of host protein, with a decrease in lean body mass and body fat depletion occurring in parallel to neoplastic growth. Since leucine is one of the principal amino acids used by skeletal muscle for energy, we investigated the changes in body composition of pregnant tumor-bearing rats after a leucine-supplemented diet. Sixty pregnant Wistar rats divided into six groups were fed a normal protein diet (18%, N) or a leucine-supplemented diet (3% L-leucine, L). The pregnant groups were: control (CN), Walker 256 carcinoma-bearing rats (WN), control rats pair-fed with tumor-bearing rats (pfN), leucine-supplemented (CL), leucine-supplemented tumor-bearing (WL), and leucine-supplemented rats pair-fed with tumor-bearing rats...

The urethral muscle of diabetic pregnant rats is affected by long-term mild diabetes and short-term severe diabetes, which plays a crucial role in the pathogenesis of pelvic floor disorders. We hypothesized that muscles outside the pelvis are subject to similar changes. The current study aimed at analyzing the effects of long-term mild and short-term severe diabetes on the structure and ultrastructure of fiber muscles and collagen in rats' rectus abdominis (RA) muscle. Therefore, the RA muscle of virgin, pregnant, long-term mild diabetic, short-term severe diabetic, long-term mild diabetic pregnant and short-term severe diabetic pregnant 3-month-old Wistar rats were collected. The structure was analyzed by picrosirius red staining, immunohistochemistry for...

During pregnancy and protein restriction, changes in serum insulin and leptin levels, food intake and several metabolic parameters normally result in enhanced adiposity. We evaluated serum leptin and insulin levels and their correlations with some predictive obesity variables in Wistar rats (90 days), up to the 14th day of pregnancy: control non-pregnant (N = 5) and pregnant (N = 7) groups (control diet: 17% protein), and low-protein non-pregnant (N = 5) and pregnant (N = 6) groups (low-protein diet: 6%). Independent of the protein content of the diet, pregnancy increased total (F1,19 = 22.28, P &lt; 0.001) and relative (F1,19 = 5.57, P &lt; 0.03) food intake, the variation of weight (F1,19 = 49.79, P &lt; 0.000) and final body weight (F1,19 = 19.52, P...

Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Arguelles,J.; Diaz,J.J.; Malaga,I.; Perillan,C.; Costales,M.; Vijande,M.
Popular science has emphasized the risks of high sodium intake and many studies have confirmed that salt intake is closely related to hypertension. The present mini-review summarizes experiments about salt taste sensitivity and its relationship with blood pressure (BP) and other variables of clinical and familial relevance. Children and adolescents from control parents (N = 72) or with at least one essential hypertensive (EHT) parent (N = 51) were investigated. Maternal questionnaires on eating habits and vomiting episodes were collected. Offspring, anthropometric, BP, and salt taste sensitivity values were recorded and blood samples analyzed. Most mothers declared that they added "little salt" when cooking. Salt taste sensitivity was inversely correlated...

Differential expression of microRNA-411 and 376c is associated with hypertension in pregnancy
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Yang,Hui-li; Zhang,Hong-zhi; Meng,Fan-rong; Han,Shu-yi; Zhang,Miao.
Preeclampsia is a major reason of morbidity and mortality in pregnant women and perinatal fetus. Hence, it is of prime importance that diagnostic markers are defined to predict chances of preeclampsia in pregnant women. It has been previously shown that microRNA (miRNA)-376c expression is decreased in the placenta of preeclampsia patients at term. Even though this decrease was not mimicked in the placenta at the pre-term stage, miR-376c expression was decreased in the plasma of these patients as early as the second trimester. Plasma and placenta specimens were obtained from pregnant women having unifetal gestation undergoing perinatal care between January 2014 and December 2016 (n=49). Early trimester placentas were collected from patients undergoing...

Perinatal development and adult blood pressure
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Ashton,N.
A growing body of evidence supports the concept of fetal programming in cardiovascular disease in man, which asserts that an insult experienced in utero exerts a long-term influence on cardiovascular function, leading to disease in adulthood. However, this hypothesis is not universally accepted, hence animal models may be of value in determining potential physiological mechanisms which could explain how fetal undernutrition results in cardiovascular disease in later life. This review describes two major animal models of cardiovascular programming, the in utero protein-restricted rat and the cross-fostered spontaneously hypertensive rat. In the former model, moderate maternal protein restriction during pregnancy induces an increase in offspring blood...

Autores: Zemunik,T.; Peruzovic,M.; Capkun,V.; Zekan,L.; Tomic,S.; Milkovic,K.
Ten Fisher rats 50 to 55 days of age made up the pubertal group, and ten rats 90 to 95 days of age served as the controls. The testicular and epididymal weights and volumes of the pubertal males were lower than those of the controls (P&lt;0.001). There was also a difference in relative epididymal weight (P&lt;0.001). The sperm of pubertal males was morphologically abnormal in 58.2% of cases, as opposed to only 3.8% in the controls (P&lt;0.001). The mean number of spermatozoa in the control group was 11.9 × 10(6)/ml and their viability was 99.6%, while these values could not be determined for pubertal rats. Serum testosterone was higher in the pubertal animals than in the controls (2.52 ± 1.46 vs 0.92 ± 0.34 nM, P&lt;0.01). The ovaries of control females...

The visual system of women changes during pregnancy. Few reports have addressed the effects of pregnancy on color vision. We aimed to compare the color vision of women in the first, second, and third trimesters of pregnancy. Fifty women were divided into first (n=10), second (n=10), third trimester pregnancy groups (n=10), and non-pregnant group (n=20). We used the Farnsworth D15 and Lanthony desaturated D15 (D15d) tests. The hue ordering quantified the amount of error (C-index) and the chromatic selectivity of the errors (S-index). Bland-Altman analysis was applied to the hue ordering data. No difference was found for Farnsworth D15 test results obtained from the pregnant groups and the non-pregnant group (P&lt;0.0083). For the Lanthony D15 desaturated...

The prevalence of smoking during pregnancy in Ribeirão Preto, a rich Brazilian city, was significantly higher (21.4%) than in São Luís (5.9%), a less developed city. To assess which variables explain the difference in prevalence of smoking during pregnancy, data from two birth cohorts were used, including 2846 puerperae from Ribeirão Preto, in 1994, and 2443 puerperae from São Luís, in 1997/98. In multivariable analysis, risk of maternal smoking during pregnancy was higher in São Luís for mothers living in a household with five or more persons (OR = 1.72, 95%CI = 1.12-2.64), aged 35 years or older (OR = 1.98, 95%CI = 0.99-3.96), who had five or more children (OR = 2.10, 95%CI = 1.16-3.81), and whose companion smoked (OR = 2.20, 95%CI = 1.52-3.18).

Lysine requirements for gain in maternal body reserves and piglet birth weight, during pregnancy, in contemporary prolific genotypes, are not well established. This study aimed to evaluate the effect of dietary lysine in late pregnancy on piglet birth weight, and on the gestational and lactational performance of gilts. Pregnant gilts were uniformly distributed into two groups and received, from 85 to 110 days of gestation, either of two lysine levels in their diet: Control group - 28g lysine/day (n=136), and Lysine group - 35g lysine/day (n=141). There were no effects (P&gt;0.10) of supplemental lysine on body weight and backfat (BF) gain of females or on piglet birth weight. Gilts supplemented with lysine tended to have a lower percentage of stillbirths...

ABSTRACT: This research aimed to determine incidence of  Toxoplama gondii infection in Corriedale sheep in southern Brazil during pregnancy and the extent of associated losses. Blood samples were collected from 411 Corriedale sheep in two flocks at different locations in the state of Rio Grande do Sul (Brazil). Presence of  T. gondii was diagnosed by the Indirect Fluorescent Antibody Technique (IFAT). Seroprevalence of  T. gondii during pre-mating was 20.2%, with no significant difference between the two flocks studied. Infection by  T.  gondii was influenced by ewes'age (P≤0.05). The pre-mating seroprevalence did not influence either returning to estrus or pregnancy rates. Weaning rate was significantly higher in pre-positive dams compared to negative...

SEROLOGICAL SCREENING FOR INFECTIOUS CATTLE DISEASES: I. INFLUENCE OF REPRODUCTIVE STATUS
Provedor de dados: Ciência Rural
Autores: Barajas-Rojas,Jose Alfonso; Riemann,Hans; Franti,Charles.
A cohort of 125 cows (Zebu-Holstein crosses) were screened every two months during a period of two years for IgG antibodies to 20 viral, bacterial, rickettsial and parasitic agents. The screening was performed on sera using the ELISA procedure. The IgG levels fluctuated during pregnancy in a regular and similar way for all the antigens tested. IgG reached its lowest levels in the fourth and seventh month of pregnancy, a significant increase ocurred during the last month of pregnancy and this was followed by a precipitous decline during the first month post partum. The IgG fluctuations associated with the different phases of reproductive status may interact with seasonal changes in IgG levels. The changes in IgG levels during pregnancy may have the result...

Autores: Almeida,Vívian Tavares de; Uscategui,Ricardo Andres Ramirez; Silva,Priscila Del Aguila da; Avante,Michele Lopes; Simões,Ana Paula Rodrigues; Vicente,Wilter Ricardo Russiano.
ABSTRACT: Throughout pregnancy, maternal hemodynamic adaptation is needed to ensure proper uterine perfusion and fetal development. When the uteroplacental vascular system is formed, starting with reduced resistance to uterine arterial flow, this results in decreased total vascular resistance, an activation of neuroendocrine vasoactive peptides, an increase in circulating blood and changes in the cardiovascular system morphophysiology to respond to the increasing demands of uterine perfusion. There has been considerable study of hemodynamic adaptation in pregnant women and this assessment has become a diagnostic tool for fatal obstetric disorders. However, in bitches the available information in this regard is limited; therefore a parallel was drawn...
